How to replace shock absorber struts on a ŠKODA Octavia A5: detailed instructions with photos and videos

Shock absorber struts on ŠKODA Octavia A5 (body 1Z3, 2004–2013) is one of the key suspension elements responsible for comfort, handling and safety. Over time, they wear out: knocking noises appear, road grip deteriorates, and the car begins to “nod” when braking. If you notice these symptoms, it's time to consider a replacement. In this article we will look at how to change the front and rear struts yourself, what tools you will need, and what to look for when choosing spare parts.

The procedure is not the simplest, but can be done in a garage with minimal experience. The main thing is not to rush and follow the instructions. We will describe each stage in detail, point out typical mistakes and give recommendations for choosing shock absorbers (from budget Monroe up to bonus Bilstein B4/B6). We will also provide a comparative table of original and analog parts so that you can choose the best option in terms of price and quality.

Signs of faulty shock absorber struts on Octavia A5

The first signal that the struts are out of order is a change in the behavior of the car. On Octavia A5 With worn shock absorbers the following are often observed:

• 🔊 Knocks or squeaks when driving over bumps (especially at low speeds). The source of the sound is the upper supports or worn bushings.
• 🚗 Deterioration in handling: the car “floats” on the road, holds its trajectory worse in turns, and requires constant steering.
• 🛑 Longitudinal pecks when braking or accelerating, the nose of the car sharply “dives” forward or the rear part squats.
• 💧 Oil leaks on the shock absorber body. Even small marks indicate loss of tightness and imminent failure.
• 🔄 Uneven tire wear. If the treads are wearing away in patches or on the inside/outside, the struts may be to blame.

On Octavia A5 with 1.6 MPI, 1.8 TSI or 2.0 TDI engines shock absorber wear is especially noticeable due to the stiffer suspension compared to younger models ŠKODA. For example, on versions with a sports setting (Sportline) the racks “die” faster due to the increased load.

You can check the condition of the shock absorbers yourself:

1. Swing the car by the front/rear fender and release. If the body makes more than 1-2 oscillations, the struts are faulty.
2. Inspect the anthers and bump stops. Cracks or deformations are a reason for replacement.
3. Check the play in the upper supports by rocking the strut by hand (with the wheel removed).

⚠️ Attention: On Octavia A5 with the system DSG Worn rear struts can cause jerks when shifting gears due to sagging of the stern and changes in the angle of the box.

Which shock absorber struts to choose for replacement?

There are dozens of options on the market - from cheap Chinese analogues to original parts VAG. We analyzed popular brands and compiled a rating based on price/quality ratio:

Brand and model	Type	Average price (per 1 piece)	Features	Recommendation
VAG (original)	Gas-oil	8 000–12 000 ₽	Catalog numbers: 1Z1 413 031 J (before), 1Z5 513 025 (back). Full compliance with factory parameters.	⭐ Best choice for durability
Bilstein B4	Gas-oil	6 500–9 000 ₽	Analogue of the original, but with improved thermal stability. Suitable for aggressive riding.	⭐ Optimal for most
Monroe G4748 (before) / G4749 (back)	Gas-oil	4 000–5 500 ₽	Budget option with good reviews. Softer than the original, but less durable.	⚠️ Suitable for relaxed driving
Kayaba (KYB) Excel-G	Gas-oil	5 000–7 000 ₽	Stiffer than standard, improved handling. Often installed on tuned Octavias.	⭐ For lovers of sports driving
Sachs Super Touring	Gas-oil	5 500–8 000 ₽	Soft, comfortable, but can “sag” with frequent loads.	⚠️ Only for urban use

When choosing, pay attention to catalog numbers:

• 🔧 Front struts: 1Z1 413 031 J (left), 1Z1 413 032 J (right). For versions with Haldex (all-wheel drive) — 1Z5 413 031.
• 🔧 Rear shock absorbers: 1Z5 513 025 (for sedans), 1Z5 513 026 (for station wagons Combi).

Do not buy racks based on the “cheaper” principle - cheap analogues (for example, Febi or Topran) often flow after 20–30 thousand km. Also check the package contents: the box should contain bumpers, boots and upper supports (unless they come separately).

Tools and preparation for replacement

To replace racks with Octavia A5 you will need:

• 🔧 Special ties for springs (required!) Without them, it is dangerous to take apart the rack.
• 🔧 Torque wrench (for tightening nuts with a moment of 50-60 N·m).
• 🔧 Socket heads 13, 16, 18 and 21 mm (for unscrewing the bolts of levers and racks).
• 🔧 6 mm hexagon (For the purpose of fixing the shock absorber rod when unscrewing the nut).
• 🔧 WD-40 or equivalent Bolts are often clamped, especially in the rear suspension.
• 🔧 Jack and stops (or lift). Working on a “one-jack” is prohibited!

Also prepare:

• 📦 New dusters, breakers and upper supports (If they are not in the same place as the sacks).
• 🧴 Graphite grease for processing threaded connections.
• 🧤 Gloves and safety glasses — springs under tension can cause injury.

⚠️ Attention: On Octavia A5 with engines 1.8 TSI or 2.0 TDI Before replacing the front pillars must be removed adsorber (interfering with dismantling). Don't hurt her or she'll catch fire. Check Engine.

Before starting work:

1. Place the machine on a flat surface and secure the wheels with chocks.
2. Relax the wheel nuts and rack bolts before lifting on the jack.
3. Open the hood and remove the plastic cover above the upper support (if it interferes).

Step-by-step replacement of front shock absorbers

Front struts on Octavia A5 They change more difficult than the rear ones because of the need to disassemble the turning fist. Follow the instructions:

1. Remove the wheel And clean the dirt around the rack bolts. Process them. WD-40 and wait 10–15 minutes.
2. Unscrew the ball-support nut. (key 18 mm) and press your finger out of the lever with the mount. Don't hurt the anther!
3. Turn the bolts of the mounting of the rack to the turning fist (2 pcs., head by 16 mm). You may need to hold the bolts on the back.
4. In the engine compartment unscrew 3 nuts of the upper support (13 mm wrench). Support the stand so it doesn't fall.
5. Remove the rack in the assembly And put her in the vise. With the help of screeds, squeeze the spring until the upper nut is weakened.
6. Unscrew the shock absorber rod nut (key 21 mm + hexagon 6 mm for fixing the rod).
7. Disassemble the rackRemove the spring, the support and the jack. Check them for wear and tear.
8. Get a new rack. in reverse order. Make sure the spring is standing bottom turn into the groove of the cup.
9. Put the rack in place.Tighten all bolts with a force of 50-60 Nm. Twisted the rod nut. only after the suspension is fully loaded (the car must be on wheels).

When assembling, pay attention to:

• 🔄 Correct position of the spring - the upper turn should rest on the protrusion of the support.
• 🔧 Tightening torque nuts:
  • Shock absorber rod nut - 55 Nm.
  • Bolts securing the strut to the knuckle - 90 Nm.
  • The nuts on the top support. 20 Nm.

After replacement be sure to do a wheel alignment! Even if you carefully assemble everything by the labels, the angles of the wheels installation will change.

Replacement of rear shock absorbers: nuances and differences

Rear pillars Octavia A5 They change more easily than the front ones, but there are their own characteristics:

1. Remove the wheel and unscrew the bottom bolt of the shock absorber attachment to the lever (head 18 mm).
2. In the trunk, remove the plastic cladding and unscrew the top nut of the rack (key 16 mm).
3. Remove the shock absorber along with the spring. Back axle, rack and spring. loosely (unlike the front one), so there is no need to disassemble anything.
4. Compare the new and old racks - the length should match. If the new one is shorter, it may have already “sank”.
5. Install a new shock absorbertighten the bottom bolt with force 70 NmThe top nut is the top nut. 40 Nm.

Important points:

• 🔧 On station wagons Octavia Combi The rear racks are longer than on sedans. Check the catalog number!
• 🔧 If the spring is “tired” (slit or cracked), replace it with a rack. Standard stiffness of springs for Octavia A5 — 230-250 N/mm.
• 🔧 After replacement, check operation rear-suspensioner (if there is one). If the installation is incorrect, an error may occur. P1650.

⚠️ Attention: On machines with the system 4Motion (all-wheel drive) rear racks have a reinforced design. Install only details with a mark. 4WD in the catalog.

What to do if the rear suspension knocks after the replacement?

Knocking may occur due to:

1. Insufficient tightening of bolts (check the moments).

2. Wearing of the bushings of levers or Bushings (replace together with the racks).

3. No gasket between the spring and the cup (install a rubber pad).

4. Defect of the new shock absorber (check for the beating of the rods).

Common mistakes when replacing racks and how to avoid them

Even experienced masters sometimes make mistakes that lead to the imminent failure of the racks or deterioration of controllability. Here are the most common:

• ❌ Incorrect tightening of nuts:
  • If the shock absorber rod is tightened before the rack is installedThe spring will not work properly.
  • A weak tightening of the bolts of the rack attachment to the fist leads to backlash and knocks.
• ❌ Ignoring the top supports. Their resource is 100-150 thousand. km. If the support "crunchy" or has a backlash, change it along with the counter.
• ❌ Installation of springless racks. This is deadly - the spring can "shot" and cause serious injuries.
• ❌ Savings on breakers and anthers. Without them, the shock absorber will quickly fail due to dirt and mechanical damage.
• ❌ Failure to follow the assembly order. For example, if you forget to install a gasket between the spring and the cup, a metal knock will appear.

Another common problem is incompatibility of spare parts. For example:

• 🚫 Racks from Octavia A4 (body 1U) are not suitable for A5 due to different fastenings.
• 🚫 Shock absorbers for the sedan are not put on Combi (and vice versa) - different length.
• 🚫 Stacks for versions c Haldex They are not interchangeable with front-wheel drive.

How much does it cost to replace the service?

If you are not confident in your abilities, you can trust the replacement of racks to professionals. The cost of work depends on the region and level of service:

Total cost of replacement of a set of racks (4 units) with work and spare parts:

• 💰 Budget option (racks Monroefoothold Febi) — 25 000–35 000 ₽.
• 💰 Middle segment (racks Bilstein B4foothold Lemforder) — 40 000–60 000 ₽.
• 💰 Premium (original VAG or KYB Excel-G) — 60 000–90 000 ₽.

You can save if you buy spare parts yourself (services often throw 20-30% on the price) and negotiate a replacement with your parts.

FAQ: Frequent questions about replacing racks with Octavia A5

Can you replace the front and leave the back?

Technically yes, but not recommended. The rear shock absorbers wear out more slowly, but if they are already "tired", the car will tilt back when braking. It is optimal to change all 4 racks with a set. If the budget is tight, start with the front ones – they have more impact on manageability.

How often should I change the racks on the Octavia A5?

The service life depends on the style of driving and the quality of the roads:

• 🚗 Original racks — 100,000–150,000 km.
• 🚗 High-quality analogues (Bilstein, KYB) - 80,000–120,000 km.
• 🚗 Budget racks (Monroe, Sachs) 50,000-80,000 km.

Check the condition of shock absorbers every 20,000 km or if you experience wear and tear symptoms.

What happens if you drive on worn struts?

The consequences are serious:

• ⚠️ Increased braking distance 20-30% due to the smearing of the body.
• ⚠️ Risk of aquaplaning The wheel loses contact with the road on irregularities.
• ⚠️ Accelerated wear of tires, ball supports and bushings.
• ⚠️ Body damage When it hits the hole, the shock absorber does not extinguish the blow.

At speeds over 100 km/h, worn-out racks can lead to loss of control!

Do I need to do a wheel alignment after replacing the struts?

✅ Definitely! Even if you carefully assemble everything by the labels, the angles of the wheels installation will change. Nana Octavia A5 Incorrect collapse leads to:

• Uneven wear of tires (5,000 km can "eat" the tread to the cord).
• The car pulls to the side when driving in a straight line.
• Increased fuel consumption by 5–10%.

The cost of adjustment (1500-2500 rubles) will be paid off with money saved on tires and fuel.

Is it possible to restore old racks?

Theoretically yes - some workshops offer bulkhead shock absorbers (replacement of oils, adding oil, pumping). However:

• ❌ Restoration quality It depends on the master. Often after repair, the racks flow in 10-20 thousand. km.
• ❌ Cost (3000-5000 rubles per piece) is comparable to the price of new budget shock absorbers.
• ❌ No guarantee Original racks give a guarantee of 1-2 years, restored - no.

It is more profitable to buy new racks of the middle price segment.
